I have three fans on my pool deck and I would like to be able to control the fan speeds of all three at the same time from one control. I would want them all to run at the same selected speed. Does anyone know of a wall mounted fan speed control device that will control three ceiling fans Instead of one) at one time. I know I can use three remote control units all set to the same code as a single hand control unit, but I really want a wall mounted control.
